2016-10-15procfs: Gracefully degrade meminfo.Justus Winter
* procfs/rootdir.c (rootdir_gc_meminfo): Just omit the swap information if the default pager is unreachable.
2016-03-24Use swapon path as pager partition pathSamuel Thibault
When /dev/hd* entries are parted-partition storeio, the store name is only the disk name, thus not unique. We should just use the path being used instead. * sutils/swapon.c (swaponoff): Use `file' instead of `store->name' to default_pager_paging_file. (main): Drop hardcoded "/dev/". * procfs/rootdir.c (rootdir_gc_swaps): Drop hardcoded "/dev/".
2016-03-24Fix swap information numbersSamuel Thibault
* procfs/rootdir.c (rootdir_gc_swaps): Fix default_pager_storage_info call parameter order. * sutils/swapon.c (main): Likewise.
2016-03-21netfs: Remove global reference count lock.Flavio Cruz
* libnetfs/drop-node.c: Remove use of netfs_node_refcnt_lock. * libnetfs/init-init.c: Remove netfs_node_refcnt_lock. * libnetfs/make-node.c: Initialize refcounts in refcounts_init. * libnetfs/netfs.h: Use refcounts_t for tracking node references. Remove netfs_node_refcnt_lock. Add netfs_nref_light, netfs_nrele_light and handler netfs_try_dropping_softrefs. Adjust comments. * libnetfs/nput.c: Use refcounts_t. Call netfs_try_dropping_softrefs to remove any soft reference that the translator might have acquired during the lifetime of the node. Implement empty netfs_try_dropping_softrefs. * libnetfs/nref.c: Implement netfs_nref_light. * libnetfs/nrele.c: Use refcounts_t and netfs_try_dropping_softrefs. Implement netfs_nrele_light. * ftpfs/dir.c: Use netfs_nref without locking the old netfs_node_refcnt_lock. * ftpfs/node.c: Likewise. * usermux/mux.c: Use netfs_nref to increase hard references of the node. * hostmux/mux.c: Use netfs_nref to increase hard references of the node. * trans/fakeroot.c (new_node): Use a light reference when storing a node in the hash table. * trans/fakeroot.c (netfs_try_dropping_softrefs): Implement netfs_try_dropping_softrefs to remove the node from the hash table. * trans/fakeroot.c (netfs_node_norefs): Remove code to remove the node from the hash table. * trans/fakeroot.c (netfs_S_dir_lookup): Simplify lookup code since we don't need to lock netfs_node_refcnt_lock anymore. * procfs/netfs.c: Remove use of netfs_node_refcnt_lock. * nfs/cache.c: Add mutex to handle exclusive access to nodehash. This replaces the use of netfs_node_refcnt_lock. * nfs/cache.c (lookup_handle): Use nodehash_ihash_lock when accessing nodehash. Use netfs_nref_light to add one soft reference to the node just added to nodehash. * nfs/cache.c (netfs_node_norefs): Use netfs_nref. Don't use netfs_node_refcnt_lock and don't remove the node from nodehash here. * nfs/cache.c (netfs_try_dropping_softrefs): Drop the light reference when the node has no more hard references. * nfs/cache.c (recache_handle): Use nodehash_ihash_lock instead. * nfs/ops.c (netds_attempt_unlink): Use refcounts_references. * console/console.c (netfs_node_norefs): Use a soft reference to store a node in dir_node, cons_node, disp_node, inp_node. * console/console.c (netfs_try_dropping_softrefs): When dropping all soft references remove node pointer from the fields above.

2015-12-31Drop OTHERLIBS and use LDLIBS exclusivelyFlavio Cruz
When cross-compiling, OTHERLIBS magically turns -lpthread into the path to the host libpthread.so file, resulting in build issues.
